Application April 5, 1941, Serial No. 387,035 2 Claims. (01. 209-370) This invention relates to improvements in a;

combination pouring spout and sifter adapted to be either permanently or removably attached to cartons containing cake flour and the like.

One of the principal objects of the invention is the provision of an article of this character which may be quickly and conveniently attached.

to a carton either during the manufacturing of the carton, during the filling operation, or applied by the user after purchasing a filled carton.

A further object is the provision of a closure plate hinged to the forward end of the article to close the aperture in the carton, and so formed that when moved into an open position, it provides a pouring spout.

The foregoing and other objects will appear as I H my invention is more fully hereinafter described in the following specification illustrated in the accompanying drawing and the appended claims,

In the drawing:

Figure 1 is a perspective view of a carton showing the device applied to one wall thereof and with the pouring spout in a closed position to form a seal.

Figure 2 is a slightly enlarged, fragmentary view of Figure 1 showing the pouring spout in open position.

Figure 3 is a perspective view of the combinationsifter and pouring spout in the form adapted to be applied to the carton during its manufacture.

Figure 4;- is applied to a carton.

Figure 5 is a perspective view of a modified form of the invention wherein the bottom and side walls of the device are formed with cutting edges enabling it to be thrust through the wall of a filled carton to cut its own aperture.

Referring now more particularly to the draw- In Figure 3, reference numeral I indicates the main body of the device comprising a flat bottom wall 2 and rearwardly tapering angular side walls, 3 and 4. The top surface of the device is formed with a rim or flange 5 to which is attached by any suitable means, such as, solder or the like, a screen 6 to serve as a sitter.

Pivotally mounted, as at l', to the flange at the inner end of the device is an agitator, generally indicated at 8, and consisting of a triangularshaped framework formed with ribs 9 diverging from and preferably made integral with a plate l0 which is held in sliding contact with the flange II at the open end of the device by a finally pointed out in a top plan view of the device shown I of the'fiange II. The ID is provided with an portion i2 punched out forward end of the plate actuating handle l3 by means of a hinge I4, which normally allows the handle to be suspended from the plate ill in a vertical position, as shown, so as not to interfere with the closing operation of the pouring spout. The rearward end of the frame 8 is formed with vertical projections 15 to further agitate the contents of the carton upon swinging the agitator about its pivot point I.

. To the forward end of the bottom wall 2, I attach, by any approved type of hinge, a pouring spout comprising a bottom wall l6 and two integral side walls ll, whose upper rear ends are formed with projections 18 adapted to bear against the inner surface of the wall of the carton, and to serve as limit stops when moving the spout into an open position. The spout is attached to the floor 2 by any suitable type of hinge, as aforesaid, located along the line iii, if the device and pouring spout are made of metal. If, however, the bottom and side walls of the sifter and pouring spout are made of cardboard, or the like, then a hinge may be formed by a fold-line located, as at l9.

In the form of the invention illustrated in Figure 5, the body of the sifter, as well as the pouring spout, is made of metal; and the upper edges of the side walls are formed with cutting edges 20. The bottom wall 2| is preferably pointed, as at 22 and also sharpened so that the device may readily out its own aperture through the wall of the carton to which it is to be applied. The forward ends of the frame for the sifter terminate in a frame 23, formed with an integral projection 24 tilted upwardly, and preferably rolled back on itself, as at 25, to provide a cam or lifting surface for the punched-out flap of the carton formed by the cutting walls. In this form of the invention, the sifter, the agitator, and its handle are identical with those shown and described in connection with Figure 3. The pouring spout is attached to the frame 23 by a hinge 26. This form of the invention may be conveniently thrust through the wall of the carton and moved inwardly to a position where the frame 23 bears firmly against the outer surface of the wall of the carton. To make the attachment more permanent, an adhesive may be applied to the inner surface of the frame for causing it to adhere to the wall of the carton. One of the features of the frame is that it provides reinforcement for that portion of the carton wall in which the aperture has been formed.

While I have shown a particular form of emed across the side walls, an agitator swingably I mounted with respect to the sifter and provided-y;

with a hingedly mounted handle, a pouring spout. 5

the body member hinged to the forward end of and adapted when in a closed position to seal the aperture formed in the carton for the insertion of the body member.

2. A combination sifter and pouring spout for cartons, comprising a hollow body member having a bottom wall and two rearwardly tapering side walls, a pouring spout hingedly mounted to the forward end of the bottom wall, a sifter of flat formation mounted upon said Side walls, an agitator swingably mounted above the sifter and in wiping contact therewith, said body member being of greater width than the pouring spout, whereby the front edges of the body member will bear against the marginal edges of an opening in the carton through which the pouring spout may be swung to an open or closed position with respect thereto.
